Anne Hathaway, Jennifer Hudson, and Kim Kardashian's Workout Plans

Celebrities Anne Hathaway, Jennifer Hudson and Kim Kardashian all have super bodies that they work hard to maintain. Along with incredible poise, talent and beauty, these women also put in the blood, sweat and tears to look the way they do.

So how do these lovely ladies get their envious shapes? Read on!

Anne Hathaway

The dark-haired star with the beautiful eyes is used to putting in serious gym time in order to maintain her fabulous 5'8" frame. When getting ready to film "Get Smart" in 2007, Hathaway trained with Ramona Braganza, the man credited with helping to create Jessica Alba's incredible figure.

Braganza told People, "I treated her the way I would train an athlete because there was a lot of agility and balance involved with martial arts. So you don't do anything sitting down. You do everything standing up or on one leg."

More recently when "The Devil Wears Prada" star prepared to co-host the Oscars this past February with James Franco, Anne turned to her personal trainer David Kirsch and his gym in a bag.

Said Kirsch, "Anne has my routine down. With the gym in a bag she can fit workouts in when and where she wants them. Click here to learn more about the tools that Anne used to get into shape from David Kirsch's $75 gym in a bag.

Jennifer Hudson

The former American Idol alum has morphed from a size 16 to a size 6 via Weight Watchers and some serious training with celebrity trainer Harley Pasternak. In fact, Hudson even had some people wondering if she'd lost too much weight when she presented an award at the Academy Awards in February.

However, Hudson has lost a total of 80 pounds since starting her journey and recently told Oprah Winfrey that she has no intentions of losing any more weight. Said Hudson, "I like meat on my bones now. That four and that two and that zero is not for me."

In addition to following the Weight Watchers Points System, the mother to 20-month-old David has followed the fitness part of Harley's Five Factor Diet and Fitness regimen.

Harley's fitness plan is comprised of five factors including a five minute warm up, five minutes each on upper body, lower body, abdominals, and finally five minutes spent cooling down. Hudson reportedly works out five times a week using this system.

Kim Kardashian

Kim Kardashian is one of those rare women who have all the right curves in the correct places on her body. With an hourglass figure reminiscent of Hollywood legends like Sophia Loren and Jayne Mansfield, many question if the reality TV star was simply blessed with that figure and doesn't have to do much to maintain it.

Not so! The "Keeping Up with the Kardashians" star has proven over the years that her weight does fluctuate and she has to work hard to maintain her shape.

Kim has created a series of workout DVDs called "Fit In Your Jeans By Friday" which include a workout for butt and body toning, abs, and butt cardio using steps.

Additionally, the famous middle sister between Kourtney and Khloe said that she's working out harder than ever as bikini season is almost here. Click here to see Kim's tips for working out and photos of her gorgeous figure.
